Magento – Group price for product

Below is the way to get

/** @var \Magento\Catalog\Pricing\Render\FinalPriceBox $block */
$productId = $block->getSaleableItem()->getId();

// START
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$_product = $objectManager->create('Magento\Catalog\Model\Product')->load($productId);

$productAllTierPrices = $_product->getData('tier_price');

$allTierPrices = array();
foreach($productAllTierPrices as $tierPrices){
    $groupname = $objectManager->create('Magento\Customer\Model\Group')->load($tierPrices['cust_group'])->getCustomerGroupCode();
    $allTierPrices[$groupname] = $tierPrices['price'];
}

echo "<pre>";
print_r($allTierPrices);
exit;
// END

How to avoid ObjectManager in above code? If you know then can update the answer or post own.

Thanks

Here $product is the product Object.

Group Price:-

$roleId = Mage::getSingleton('customer/session')->getCustomerGroupId();
$grp_price = $product->getData('group_price');
$customer_groupprice = $grp_price[$roleId]['price'];

Here the current customer Group ID $roleId. $customer_groupprice is the customer Group Price.

Tier Price:-

$roleId = Mage::getSingleton('customer/session')->getCustomerGroupId();
$TierPrice = $product->getData('tier_price');
$customer_grouptier = array_column($TierPrice, 'price','cust_group');
$customer_tier = $customer_grouptier[$roleId]; 

Below the Conditions to check whether the Tier and Group Price Set or not

if(!empty($customer_groupprice))
{
echo "Customer Group Price is set";
}
else
{
echo "Customer Group Price Not Set";
}

if(!empty($customer_tier))
{
echo "Customer Tier Price is set";
}
else
{
echo "Customer Tier Price Not Set";
}
